Specification of Letters Patent.

Patented Sept. 18, 1906.

Application filed August 30, 1905. Serial No. 276.352.

To all whom it may concern:

Be it known that we, THOMAS BENTON DORNAN and NATHANIEL MARCUS SHINN, citizens of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Pile-Fabric Looms, of which the following is a specification, reference being had therein to the accomp anying drawings, forming a part thereof.

Our invention relates to warp-crossing mechanism for crossing pile-warp threads over longitudinal pile-wires, and has for its objects simplicity of construction, ease of insertion of warp-threads, permanency of adjustment and durability, ease of operation, and certainty and reliability of operation.

Our invention obviates the use of addi tional reeds or combs, such as have heretofore been employed to effect this crossing operation and which have provided one or more additional parts through which the warp-tlncads must be inserted. in placing them in the loom, and our invention provides pile-warp deflectors of strong and simple construction, combined with pile-wires which may be of ordinary construction to positively effect the crossing operation with the expenditure of slight power.

e will now describe the constructions embodying our invention illustrated in the accompanying drawings and will thereafter point out our invention in claims.

Figure 1 is a longitudinal vertical section showing parts of a loom embodying our in vention. Fig. 2 is a detail rear end elevation of the pile-wires, pile-warp deflectors, adjacent parts, and operating mechanism with the pile-warp deflectors moved to the left extreme position. Fig. 3 is a similar view, omitting the operating cam and lever, with the pile-warp deflectors moved to the right extreme position. Fig. 4 is an enlarged end elevation, and Fig. 5 an enlarged side elevation, of a portion of a pile-warp deflector of modified construction.

The drawings illustrate only such parts of the loom as are required for an understanding of the present invention.

The lay 1 is of ordinary construction and only its upper portion, including the reed 2,

is shown, and. it is shown 1n extreme forward position, at which position the lift of the pilewarp selected to form the pile will occur in the weaving of a fabric such as shown in the loom in Fig. 1.

The pile-wires are shown as of ordinary construction and are clamped. at their front ends upon a stationary cross-bar 13 by means of a clamping-plate 24, held down by screws 25. Each pile-wire has a horizontally-extending portion 3, having a stationary knife 4 set therein, and has an upwardly and rear wardly inclined portion 5 in rear of the horizontal portion and also has an upright portion 6, forming the extreme rear portion of each pile-wire. These rear upright portions at their lower ends enter vertical grooves in a stationary cross-bar 7, this stationary crossbar being carried by an angle-beam S in the usual manner.

The pile-warp deflectors embodying the present invention are shown as secured at their lower ends to the vertical portions of the pile-wires just above the cross-bar 7, this construction being simple and obviating the formation of additional grooves in the crossbar for the pile-warp deflectors. Each pilewarp deflector consists of an upright strip 9, preferably of flat metal, as shown, secured at its lower end, as aforesaid, to the lower part of the upright portion of the pile-wire and extending upward in substantial parallelism to the upright portion of the pile-wire, but extending a considerable distance above the pile-wire and entering vertical slots in a 1novable cross-bar 10, which is fitted to slide transversely of the loom. Each pile-warp deflector 9 is provided with laterally-extending projections 11, adapted to extend over each adjacent pileire, and these projections are shown as formed so that they will closely overlie the pile-wires and have slightlyrounded corners at their lower portions, so as not to catch the warp-threads when the warp-threads are lifted, and have easy inclinations from their upper to their lower portions, so as to form guiding-surfaces for the warp-threads as the warp-threads are lowered, these guiding-surfaces performing the function of guiding the \VtL'lP-lllllCiulS from one side to the other of each pile-wire as the warp-threads are lowered.

In Fig. 2 the pile warp deflectors are shown in their extreme position to the left, and

while they are in this position the warp e, which is to form the pile, will be lifted and will pass freely upward without obstruction to a position above the pile-wires, as shown in Fig. 1. In Fig. 3 the pile-warp deflectors are shown after they have been moved to their extreme positions to the right and the parts are now in position to guide the pilewarp in its downward movement, so as to loop the warp over the, pile-wires. Here also, it will be noted, there is no obstruction to the downward movement of the warps. The lower position of the pile-warp is shown by broken lines 6 in Fig. 1. This position will be maintained until the shuttle has been thrown and the lay has beaten up the weft and until the warp to form the pile has been again lifted. The pile-warp deflectors will then be shifted to the left and the pile-warp will be lowered and guided by the pile-warp deflectors, so as to be looped back over the pile-wires. The shuttle will then be thrown and the weft beaten up. Thus the pile-warp will be positively guided and deflected through guideways of ample width for its free movement.

The movable cross-bar 10 is shown as slidably connected by screws 12, entering slots 13 in the movable cross-bar, to studs 14, secured to the upper an le-beam 15 of the loom. A connecting-rod 22 joins this movable cross-bar to an actuating-lever 16, which is pivoted at 20 and is controlled by a cam 17, the actuating-lever being provided with a cam-roller 18, working against the periphery of the cam and held a ainst the cam by the spring 19. A cam-shaft 21 is suitably geared so as to make one-half a revolution for each beat of the lay, and, as shown in Fig. 2, the cam is about to shift the pilewarp deflectors from the left to the right.

The upper ends of the pile-warp deflectors 9 enter freely and loosely into the slots provided for them in the movable cross-bar 10, and their movement is eflected by slight flexure thereof in an upright plane transverse to the loom, the amount of movement being small and requiring the expenditure of but slight power.

The other warp-threads of the fabric are shown in proper positions in Fig. l, the drag and stuffer warps d being indicated by a single line and the binder warp-threads a and I) being also shown.

In the construction of pile-warp controller above described the projections 11 are shown as formed by a thickening of the material of the warp-controllers which may be effected by suitable solder. In the modified construction shown in Figs. 4 and 5 these projections 26 are shown as formed by obliquely twisting the warp-deflectors with a comparatively sharp twist at the lower portions of each projection and a comparatively easy twist at the upper portion thereof. Obviously the operation of both constructions is the same.

It will be noted that the projections on the pile-warp deflector perform the function of guiding or deflecting the pile-warp threads during the downward movement of the pilewarp threads as above described and ma therefore properly be termed deflector projections. It will also'be notedthateach pile-warp deflector intermediate of the pilewires provides two deflector projections, one for each adjacent pile-wire, and that each pile-wire has two deflector projections cooperative with the pile-wire to deflect the pile- Warp thread to one or the other side of the pile-wire.

It is obvious that various modifications may be made in the constructions shown and above particularly described within theprinciple and scope of our invention.
